Hi, I just wanted to know the relevance of the Present Perfect Tense (I think Haal Kamil its called) in Farsi language. In what situations is its use more suitable than the use of the Present Continuous tense? For example, what is the difference between 'Man Rawanam' (I am going) and 'Man Rawandeh Am'? Also, what is meant by the Aorist tense and how is it different from the imperative? (Sir William Jones gives the imperative of 'Raftan' as 'Ro' and the aorist as 'Rawam'). What function does the aorist serve and what is the equivalent term for the aorist in Persian?
